What is a circuit a) a circuit is the same as an insulator b) a circuit is a broken loop conductive material through which electrons flow continuously. c) a circuit is a unbroken loop conductive material through which electrons flow continuously. d) a circuit is the same as a conductor

Hey there!
Your answer is C, for circuit- ironic.
Here's why:
A circuit is made of things like insulators, transistors, and conductive material, all in a loop for electricity to travel through. The loop has to be intact and be able to let electricity pass through to do its job.
Therefore, it's not the same as a conductor or insulator, and it can't be broken.
Hope this helps!
